4D trajectory optimisation has showed good potential to reduce environmental impact in aviation. However, a recurrent problematic is the loss in air traffic capacity that these pose, usually overcome with speed and time advisories. This paper aims at the quantification in terms of fuel consumption of implementing suboptimal trajectories to preserve capacity. Via an own developed optimisation framework, we deliver results on how imposing a nonoptimal RTA to a trajectory increases the fuel burned. We show how advancing a metering fix in an example departure trajectory translates to an increase of up 15Kg of fuel burned. Similarly, postponing it 50s, will burn around 23Kg more. Also, imposing a level off phase (due to incoming traffic) will typically consume around 25Kg more. Different scenarios
